Chandra Observation of Abell 2065: An Unequal Mass Merger?
Marios Chatzikos, Craig L. Sarazin, Joshua C. Kempner
We present an analysis of a 41 ks Chandra observation of the merging cluster Abell 2065 with the ACIS-I detector. Previous observations with ROSAT and ASCA provided evidence for an…
AGN feedback and gas mixing in the core of NGC 4636
E. O'Sullivan, J. M. Vrtilek, J. C. Kempner
Chandra observations of NGC 4636 show disturbances in the galaxy X-ray halo, including arm-like high surface brightness features (tentatively identified as AGN driven shocks) and a…
AWM 4 - an isothermal cluster observed with XMM-Newton
E. O'Sullivan, J. M. Vrtilek, J. C. Kempner +2
We present analysis of an XMM observation of the poor cluster AWM 4. The cluster is relaxed and its X-ray halo is regular with no apparent substructure. Azimuthally averaged radial…
Chandra and XMM-Newton Observations of the Double Cluster Abell 1758
Laurence P. David, Joshua Kempner
Abell 1758 was classified as a single rich cluster of galaxies by Abell, but a ROSAT observation showed that this system consists of two distinct clusters (A1758N and A1758S) separ…
Chandra Observation of the Core of Abell 576
Joshua C. Kempner, Laurence P. David
We present data from a Chandra observation of the nearby cluster of galaxies Abell 576. The core of the cluster shows a significant departure from dynamical equilibrium. We show th…
A Taxonomy of Extended Radio Sources in Clusters of Galaxies
Joshua C. Kempner, Elizabeth L. Blanton, Tracy E. Clarke +3
At the request of the conference attendees, we have compiled a classification of extended radio sources in clusters. These range from scales of tens of parsecs to over a megaparsec…
